Past Student Feedback

  • Prof. Bentz is one of the most engaging professors I have ever had. Coming into the class I didn’t expect the breadth of topics that I learned. Bob’s experience is great and he does a great job of leading us through learning.
  • This has been, by far, my favorite class. Rather than simply making a mobile marketing plan, we were able to do some tactical work. Prof. Bentz is super knowledgeable and his book was awesome. It was a breath of fresh air compared to traditional textbooks.
  • Bob Bentz is an excellent professor! He knows the subject like the back of his hand. Having his own business on the matter helps keep the class up to date and brings real scenarios to put in practice.
  • Prof. Bentz was attentive, responsive, and intelligent. He used a lot of video and presentation tools. The topics were current and relevant. The course work was anchored in today and tomorrow’s technology. This course will definitely go down as my favorite course.
